Under same conditions as for PVop-38, T46 burst level is
measured.
Under same conditions as for PVop-38, input chroma
level is raised by +6 dB. T46 burst level is measured
and compared to PVop-46.
Under same conditions as for PVop-38, input chroma
level is raised by –6 dB. T46 burst level is measured
and compared to PVop-38.
Under same conditions as for PVop-38, input chroma
level is attenuated and input burst level is measured
when chroma output at T46 goes off (compared to
standard input 80 mVp-p)
T38 measured with spectrum analyzer and compared to
PVop-38 in killer condition as described above.
Under same conditions as for PVop-38, T38 is measured
with spectrum analyzer and 4.43 MHz component is
compared to 5.06 MHz component.
From T15A, down-converted chroma noise test signal
mixed with 4 MHz, 300 mVp-p CW is input.
From T26A, 50% white signal is input.
–45
